To (d6 whom it may concern:

Be itlrnown that 1. JOHN F. RULE, a citizen of the United States, residing at Toledo, in the county of Lucas andState of Ohio, have invented new and useful Improvements in Apparatus for Gathering and Transferring li/i olten Glass, o't which. the following is a' specification.

My invention relates to apparatus for gathering charges or gobs of glass by suction into a transfer receptacle and transferring them'to molds or other receptacles. An object of the invention is to provide suit- 7 able means for segregating the individual charges from the supply of molten gla'ss, giving them suitable shape'for entering the molds, maintaining the glass in a hot, plastic and homogeneous condition during such transfer and quickly transferring the glass while in such condition to't he molds. A

- further feature of the invention consists in the form of the mold.

providing means for applying a reheating flame to the lower end of the gob of glass while in the transfer cup, thereby remelting the glass which has been chilled by the cutter and eliminating the shear mark. This reheating of the lass is also. of specialvalue in connection with inverted molds for form" ing bottles and the li,ke,'as itlrenders' the end of the gob which first enters the mold suiiiciently hot andplastic to readily take the invention will appear hereinafter.

and showsautransfer cup and means for opening and closing the same.- Figure 15 is a detail view of a portion of the knife operating mechanism. The u' achine as shown includes a base 20 on which .is mounted a stationary frame 21, the entire -machine being mounted on wheels to run on tracks 22 "for movingthe machine to and from-the furnace or glass tank. A horizontally disposed rectangular frame'23 is mounted for continuous rotation about a vertical non-rotating shaft 24. The

frame 23 cou'ipriscsangle bars 25 forming the sides of the frame, and transverse bars or brackets 26. A frame 27 carrying transte'r cups 28 is mounted on the frame 23 to rotate therewith'and to reciprocate horizontally thereon.

The drivin mechanism co-Inprises'an electric motor Iii mountcd'on the base 20 and operating through gears 29 and 30 to drive a horizontal shaft 31' on which is'a bevel gear 32meshing with a gear on a hori* zontal shaftfie. Motion is transmitted from the shaft 34 through bevel gears 35 and 3G to a vertical shaft 37, the upper end of .which carries a pinion 3'8 meshing with a Q gear 39 mounted concentric With the non- :rotatmg: shaft 2%. The gear 39 1s Keyed to a hub or sleeve 42 which depends from and forms part of the frame 23. It will be seen that when the motor is running, motion is transmitted through the train of gears just described to the frame 23, therebycausing the latter .to rotate continuously about its vertical axis. The frame 27 rotates with the frame. 23 and "in addition has a reciprorating movement imparted thereto by the following means:

'A mutilated gear 43is keyed to the nonrotating shaft 24 and is provided on onehalf or less ot'its periphery with gear teeth 45 Gear pinions 46 and' l-i are journalled in the frame 23 so that they revolve about the shaft 24 as a center -Wl1il said frame rotates. These pini-on's are provided with looking surfaces 48-to interlock with the wheel 43'when said pinions are in. the Figure 2 position. As the frame 23 rotates in the direction of the arrow (Fig. 2) the teeth on the pinion 46 mesh with tll-e g'ear teeth 45 on the gear 43 While said pinion 46 travels along the right hand side of said gear. The

pinion is thus rotated on its own axis and thereby drives a rackfSO which is in mesh with said pinion. The rack and a cor respond1ng,rack 51 111 mesh with the pinion 47 are secured to the frame 2?- by bolts 52 (F 1,5 1) and form part of said frame. The

-'trame- 27 is, thus driven toward the right (Fig. 2) while the pinion 46 is running in mesh with the teeth 45 on the stationaryv gear 43. In this manner the frame 27 is movedoutwardly r'elativegto its :center of rotation during substantially shalt rotatron. The gear &6 makes complete rot-ation about its'axis while the frame is making a half revolution. lThis brings the gear 46 to the lower side of the gear 43, or in other words into the ,position in which the pinion 47-is shown on Figure While the I gear 46 is in mesh withthe 43 .and driving the rack 50, the gear 457. is being: driven idly by the rack 51. During the next half revolution of the frame 23 the: pinion 47 is 'driven by-the gearteethlS and re turns the frame 27. One purpose of reciprocating the frame 27 as itrotates is to project the gathering cups 528 outwardly over the-edge of the gathering tank 54 into-position to gather the glass. Each cup is held in such projected position for a limited time while traveling over the tank. by means of theinterlocking of the gearsvas shown in Figure 2.

The tank 54- may heprovidell with aconcave jack arch 55 to expose a portion of the surface of the glass for gathering! Any 7 suitable means may be provided for maintaining movement of the glass past the gathering point if desired. such as shown,'

for example, in my co pending application, Serial Number 306,059. The glass mayalso be gathered from a revolving tank such as i is i-in common use with machines which gather by suction. 1

Therotatineframe may be given a vertical reciprocating movement to cause the gathermgcups to dip into the glass.

This reciprocating movement is efiected by a ca m 56 which is keyed to the shaft 31 to rotate therewith; This cam is provided. with a cam groovein which runs a roll 57 on an arm 58 secured to the lower end of 'the verti cal shaft 24. The frame is supported on said shaft by means of the hub 42 which rests on a shoulder 59 formed on the shaft it is lifted by the cam 56 so that itwill clear the edge of the tank. l-Vh'en the cup at the opposite end of the frame reaches the Figure 2 ered. A counter-weight (32 is connected through a lever 63 to the shaft 24 and corin terbalances the weight or part of the weight ofthe vertically moving parts. I

Each of the suction gathering cups 28 comprises. two sections seated in holders (Figs. 9 and 14:), the latter having arms 71 journalled oil a vertical. pivot pin 72 mounterl on the frame 27. A voke T5 is connected position, the frame is again'loW-- throi'lg'h links 75 to-thb mold supports T0,

The molten glass is gathered into the cups 28 by means of suction, F or this purpose a vacuum head 8? is provided for each cup. Restricted openings 88 provide communi cation between the cup cavity and the cavity in the head 87. The. air is exhausted through a flexible pipe 89 connected to said head at one end and at its opposite end con nected to a jointed pipe 92 leading to a head 93 (Figs. 6, 10, 11)., This lie-add? is mounted on the frame 23 to rotate therewith and surrounds the stationary shaft 24. The latter is provided with a longitudinal bore 95 communicating with an ennui?" iamber 96 in the head 93; A vacuum p as connected with the bore 95 at the upper end of the shaft 24 extends to any suitable source of vacuum. it will lZl'lllS be seen that the air is exhausted from the gathering cup through the passageways 88, head 8?. pipes 89, 92, head 93 and passageways 95 9?. Vacuum is supplied to each gathering up only While the latter is in gathering position over the tank, at which time a port 98 (Figs. 10 and 11) provides communication between the chamber 96 and the passageway 95. The l1ead93 is provided with two oppositely disposed ports 98 to connect the two gathering cups alternately with the vacuum,

A cutter 100 is provided in connection with each gathering cup to sever the charge of glass ther in from the glass in the tank as the cup is lifted after receiving" its charge. The knife is carried on a horizontal ar a 101 connected to a vertical 1? on shaft 1 q tlie. otter mounted to roclr i bear-mg sleeve 103 on the frame 27. A rock arm 10% on the shaft 102 is connected ti-ri'iughl a linlt 1055 to an arm 196 on a rock shaft 107. An arm 108 on the shaft 107 can roll 109 which runs on a stationary cam 110 mounted on the shaft 2 A spring 1.11 holds the roll 109 against the cam. The lrnif e is operated as the gathering cup moves beyond the Fig- 5 position, at which the cup has just received its charge. The combined radial and rotary movement of the frame 27 at this time The limits liine may be geared or alongates don when the bu rnc ;'-l:as for the burners is supplied tl rough chamber 125 from arm 1-01 is normally in apposition above the bottom of the gathering cup in order to clear the Wall of the tan but is moved downward to its cutting plane by meansiof an inclined cam slot 112 in the sleeve 1-63, in which slot Works a pin 113 on tiie sbaft 313-2..
